Time-outs in web-forms environment

Always confused with time-outs in a web-forms environment, so I wrote it in very short terms down to be memorized. Note 549735.1
on Metalink is the best source by the way where it is explained what time-outs you can use best, in this kind of environments

Three parameters of vital importance:

* FORMS_TIMEOUT to be configured in .env-file = per application, defaults to 15 minutes.
* Heartbeat to be configured in formsweb.cfg (default), or in .env-file, defaults to 2 minutes.
* Session-timeout to be configured in web.xml, for example:
<session-config>
<session-timeout>11</session-timeout>
</session-config>
